Training-related skill changes. (A) Changes of skill along training. Skill (a metric expressing shifts in the speed–accuracy trade-off function) at baseline, immediately after training (Test), 24 h later, and 7 d post-training. (B) Online learning. Online within-session gains were assessed by subtracting baseline skill scores from those measured immediately after training (test). (C) Long-term retention. To assess long-term retention, skill scores measured immediately after training were subtracted from scores measured 1 wk after training ended. Error bars depict SEM. (Ls) low stochasticity, (Hs) high stochasticity, (FR) fixed reward.
